J11: Correlation, calibration and imaging across all wavelengths (1)

Thursday, August 21  08:00-09:20,  Room #12

Radio interferometry is a well-established technique used for imaging radio sources, and an increasing number of radio telescope arrays are being built to provide unprecedented views of the radio universe. The goal is to achieve thermal noise limited images that display no residual instrumental or systematic artifacts, so that the full sensitivity of new instruments, such as the SKA, can be harnessed. The wide bandwidths and fields of view of these instruments provide unprecedented challenges, requiring new technologies, techniques and algorithms to handle the data flow and volume. This session will review the state of the art in array imaging process, and will investigate how various compute platforms match to the various stages in the data flow.
